中庸思维影响潜变量测量结果的验证

选取等效的新浪网、时光网、搜狐网和IMDb的口碑评价量表,以大学女生为调查对象,对6部热播电视剧进行口碑评价,得出中庸思维影响潜变量测评的结论.中庸思维的论证是通过研究被调查者内心已经有了一个特定打分倾向后对被测客体会如何打分来进行的,并通过计算条件均值的方法来验证.实证表明,被调查者内心有了一个特定打分倾向之后,依然会不自觉地偏向中心点给被测客体打分,验证了中国文化中中庸思维对潜变量测量的影响.另外,数据呈现出负偏现象,更多地是反映了被测客体的真实表现.     

Evaluation of scheduling strategies for a dynamic job shop in a tool-shared,flexible manufacturing environment

A two-phase approach is used to examine the impact of job scheduling rules and tool selection policies for a dynamic job shop system in a tool-shared, flexible manufacturing environment. The first phase develops a generalized simulation model and analyses 'simple' job scheduling rules and tool selection policies under various operating scenarios. The results from this investigation are then used to develop and analyse various bi-criteria rules in the second phase of this study. The results show that the scheduling rules have the most significant impact on system performance, particularly at high shop load levels. Tool selection policies affect some of the performance measures, most notably, proportion of tardy jobs, to a lesser degree. Higher machine utilizations can be obtained at higher tool duplication levels but at the expense of increased tooling costs and lower tool utilization. The results also show that using different processing time distributions may have a significant impact on shop performance.     

The recruitment and selection of hospital medical consultants

Abstract

The literature on selection has been dominated in recent decades by the ‘prediction’ paradigm. Such an approach requires a substantial number of positions to be filled in order to compute validity coefficients. There are other approaches, using a different paradigm, when concentrated on adjusting the organization and the employee. Here careful analysis of job demands is essential. This article describes such an analysis, taking the medical consultant as an example. The method can be used in an iterative way. It is useful when one has to work with small numbers of positions.     

A decision support system for the selection of a casting process using analytic hierarchy process

This paper presents an Analytic Hierarchy Process (AHP) based decision support system to select the most suitable casting process for a given product. The hierarchical structure of the proposed method allows the decision maker to compare the different casting processes using the material suitability and flexibility, geometrical complexity, dimensional tolerance and surface finish of the casting, and the cost as the criteria for selection. Judgemental inconsistency of the decision maker in selecting the casting process is taken care by ensuring that the value of consistency ratio is below (0.1). A numerical example is presented to illustrate the effectiveness of the proposed methodology for selecting the suitable casting process.     

Choosing Choices: Agenda Selection With Uncertain Issues

We study selection rules: voting procedures used by committees to choose whether to place an issue on their agenda. At the selection stage of the model, committee members are uncertain about their final preferences. They only have some private information about these preferences. We show that voters become more conservative when the selection rule itself becomes more conservative. The decision rule has the opposite effect. We compare these voting procedures to the designation of an agenda setter among the committee and to a utilitarian social planner with all the ex interim private information.     

凉山平坝彝族丧葬文化变迁的斜向性结构研究——以喜德大石头和冕宁漫水湾为个案

凉山平坝彝族主要指居住在安宁河流域平坝地区、以种植水稻为生、汉化程度较高的那部分彝族。由于与汉族接触较多,他们在语言、服饰、习俗等方面受汉文化的影响也较深。本文主要以喜德大石头和冕宁漫水湾平坝彝族的丧葬习俗为调查研究对象,在田野调查的基础上,揭示所发生的文化变迁及其影响,并认为:平坝彝族葬俗的变迁并不是单一方面所发生的文化变化,体现出的是文化叠合与文化选择的特质。     

利用最小化代价函数方法实现多窗口谱分析

利用最小化代价函数的方法推导了一种谱分析的多窗口。性能分析的结果表明，此方法与离散长球序列多窗口谱分析方法具有相当的估计偏差与方差性能。与离散长球序列多窗口相比，此方法得到的多窗口具有直观的解析表达式而无须求解矩阵的特征分解问题，因而具有较小的计算量。通过对离散白噪声与ＡＲ过程进行的多窗口谱分析对比实验，验证了此方法的有效性和正确性。     

An alternative estimator for multiple characteristics in PPS sampling

The problem considered relates to large-scale sample surveys. A new estimator of population total for the characteristics that are poorly correlated with the selection probabilities has been developed for the PPSWR sampling scheme. The relative efficiency of the proposed estimator has been studied under a super-population model. A numerical investigation into the performance of the estimator has also been made.     

跨文化交际障碍中的行为意识因素

鉴于国内的许多跨文化交际研究主要集中在纯语言的探讨和表层文化的分析上,试图从行为意识的角度出发,就思维定势、偏见意识和价值观念三大因素来分析跨文化交际中存在的障碍,从而使学习者排除跨文化交际的障碍,并从跨文化交流中获得益处。
